Zida zapakatikati zapakatikati zotenthetsera chubu chamkuwa

Kutentha kwapakatikati kwapakatikati zida zamkuwa zopangira chubu

 

1, mwachidule:

Chida cholumikizira chapakatikati chamkuwa (copper chubu) ndichoyenera kumangiriza machubu amkuwa pa intaneti (mkuwa wa alloy akunja). Kuzama kolowera ndi kuuma kumagwirizana ndi zofunikira zenizeni za makasitomala kuti akwaniritse kuchotsa kupsinjika ndi kufewetsa kwazitsulo zamkuwa. Cholinga cha mchimake wakunja.

Chiyambi cha zida Zida zonse zidapangidwa ndikupangidwa molingana ndi makina a mechatronics. Pakati pawo, wapakatikati pafupipafupi mphamvu magetsi ndi ya 6- pulse thyristor KGPS200KW/8KHZ wapakatikati pafupipafupi mphamvu magetsi, katundu ndi ya GTR mndandanda kupatsidwa ulemu ng’anjo Kutentha, ndi zida okonzeka ndi ya zotakasika mphamvu chipukuta misozi capacitor banki. . Chipangizocho chimapangidwa ndi zida zosinthira mphamvu zamanja komanso zodziwikiratu, zomwe zimangodziyimira pawokha komanso kutentha kotsekeka. Chowongolera chowongolera chakunja chimatenga PLC (Siemens) ndikuwongolera pazenera. Magawo otenthetsera amatha kulowetsedwa mosavuta pazenera lakukhudza, monga mawonekedwe a chubu chamkuwa, liwiro la kutentha, kutentha kwa annealing, ndi zina. Pambuyo pa magawo omwe alowetsedwa, dongosolo lotsekeka lotsekeka la kutentha kwapakati pamagetsi amagetsi lidzasinthiratu mphamvu yotulutsa. , potero Kukwaniritsa zofunika kupanga. Pamene gawo lina la kupanga likulephera, mphamvu yamagetsi yapakatikati imatha kutsekedwa molingana ndi kutentha komwe kumayikidwa kuti musawotche kwambiri chubu chamkuwa. Zida zimayikidwa molingana ndi zofunikira za wogwiritsa ntchito, zikuyang’anizana ndi zipangizo kuchokera kumanzere kupita kumanja, tebulo logwiritsira ntchito limayikidwa ku zipangizo zazikulu, zomwe zimathandiza kuti wogwiritsa ntchitoyo ayang’ane momwe zinthu zikupangidwira ndikuthandizira kusintha kwa magawo.

Chitetezo cha chitetezo Zida zili ndi njira zonse zotetezera chitetezo, monga chitetezo cha kuchepa kwa madzi, chitetezo cha kusowa kwa gawo, chitetezo chamakono, chitetezo chamagetsi, chitetezo chamagetsi, chitetezo cha kutentha kwa madzi, ndi zina zotero, ndipo pali chipangizo chodzidzimutsa komanso chowoneka bwino zolakwa. Zida zimakonzedwa molingana ndi 200KW, ndikusiya malire amphamvu okwanira kuti atsimikizire kupanga kosalekeza komanso kosasunthika kwa zida kwa maola 24. Ma conductor onse owonekera amaikidwa mu bokosi loyendetsa magetsi ndi loko, ndipo pali zikumbutso za chitetezo choyang’ana maso, kotero kuti palibe ngozi za chitetezo chamagetsi zomwe zidzachitike. Chida chilichonse cholumikizira chingapewe kuwonongeka kwa zida kapena chitoliro chamkuwa chifukwa cha misoperation yamanja .

Zida dongosolo The wathunthu zida chimakwirira dera pafupifupi 2000 * 1500mm, ndi pakati kutalika kwa 1000mm. Mphamvu yamagetsi imaphatikizidwa ndi thupi la ng’anjo yotentha, ndipo ma bolts owonjezera amagwiritsidwa ntchito kukonza. Zida zimapangidwa ndi cholumikizira chakunja, chomwe chitha kukonzedwa mwakufuna molingana ndi momwe malo alili, omwe ndi abwino kugwira ntchito. Kuyika kwa zida ndi kosavuta komanso kofulumira. Ogwiritsa amangofunika kulumikiza polowera madzi ndi mapaipi otulutsira madzi ndi polowera madzi ndi mapaipi otulutsira zida (nozzle imodzi panjira iliyonse yamadzi ndi potulutsa), ndikulumikiza waya wagawo atatu kumapeto kwa zida.

kutentha koyamba: 20 ℃;

Annealing kutentha: controllable ndi chosinthika mkati osiyanasiyana 600 ℃; Kuyeza kwa kutentha kwazitsulo zazitsulo zamkuwa ndi ± 5 ℃, ndi kuwongolera kutentha kwa kutentha kwa kutentha ndi ± 20 ℃.

Kutentha kwakuya: 2mm;

Liwiro la mzere wa ndondomeko: mkati mwa 30m / min (liwiro lalikulu la mzere siloposa 30m / min);

Pakati kutalika kwa mzere wopanga: 1m;

2.3 Kusankhidwa kwaukadaulo kwa zida zonse

Zida zonse zikuphatikiza makina owongolera ma frequency apakati, makina oyezera kutentha kwa ma infrared fiber optical, kutentha kotsekeka-loop control system, reactive power compensation capacitor bank, induction heat annealing ng’anjo thupi, etc.

Intermediate frequency power control system:

2.3.1 Mphamvu yapakatikati yamagetsi ndi chipangizo chamtundu wa thyristor, voliyumu yolowera ndi 380V, 50Hz, ndi mphamvu yotulutsa ndi 200KW. Mphamvu zimatha kusinthidwa pamanja kapena zokha malinga ndi kutentha komwe kumayikidwa. Ma frequency otulutsa ndi 8KHz (kutsata pafupipafupi). Mtundu wa nduna umatsimikiziridwa malinga ndi zomwe wogwiritsa ntchito akufuna, kukula kwa autilaini ndi 2000 × 1500 × 1300mm, ndipo kutalika kwapakati ndi 1000mm.

2.3.2 Cartridge type combined silicon rack

Gawo la rectifier ndi inverter la thyristor limatenga mawonekedwe aposachedwa a silicon ophatikizika okhala ndi patent application. Njira yoyika iyi imapangitsa kuti disassembly ndi msonkhano wa thyristor ukhale wosavuta komanso wasayansi. Mukalowa m’malo mwa thyristor, ingomasulani Bawuti yolimbitsa imatha m’malo mwa chinthu chilichonse cha thyristor pamsonkhano. Kuphatikiza apo, njira yoyikayi imachepetsa kwathunthu kuchuluka kwa gawo la SCR, lomwe silimangowonjezera malo ogwirira ntchito mu kabati yamagetsi, komanso kumachepetsa kwambiri kutayika kwa mzere.

2.3.3 Mphamvu yayikulu ya DC yosalala yamagetsi

Smoothing riyakitala n’kofunika kwambiri olimba magetsi, ali ndi ntchito ziwiri. Choyamba, pangani zotulukapo za rectifier kukhala zosalala komanso zokhazikika. Chachiwiri, pamene inverter thyristor ndi yochepa-yozungulira, chiwerengero cha kukula kwa nthawi yachidule chamakono ndi kukula kwazomwe zimakhala zochepa kwambiri. Ngati makonzedwe a parameter a fyuluta riyakitala ndi osamveka, mfundo yaikulu si yabwino kapena njira yopangira si yabwino, idzakhudza kwambiri kudalirika kwa ntchito yamagetsi apakati.

2.3.4 SCR yokhala ndi mphamvu zazikulu

Pofuna kuwonetsetsa kudalirika kwa magwiridwe antchito a zida, onse okonzanso ndi inverter thyristors amagwiritsa ntchito Xiangfan station-based KP yayikulu ndi silicon ya KK kuwonetsetsa kuti zidazo zikugwira ntchito mokhazikika.

2.3.5 Gwiritsani ntchito zingwe zolipirira zotsatizana ndi zofananira kuti muchepetse kutayika kwa zingwe zotumizira

Kuti muchepetse kutayika pa mzere wapakatikati wotumizira ma frequency, capacitor ya inverter imalumikizidwa mndandanda ndi mawonekedwe ofananirako voteji.

2.3.6 Main circuit parameters and component selection basis

Magawo ovoteledwa agawo lalikulu lamagetsi apakatikati akuwonetsedwa patebulo ili:

Ntchito yanthawi KGPS200/8
Mphamvu yolowera (V) 38
DC pano (A) 400
DC voteji (V) 500
Mphamvu yamagetsi yopangira coil (V) 750
Working frequency ( H z ) 800

2.3. 6 induction kutenthetsera mkuwa chubu annealing zida

Inductor imapangidwa ndi chipolopolo cha ng’anjo, coil induction, chotengera chamadzi chosapanga dzimbiri ndi ng’anjo yamoto. Coil induction imaphatikizidwa ndi magawo a chubu cha alloy copper annealed kuti mukwaniritse mapangidwe ndi mapulogalamu apadera apakompyuta ndikupangitsa kuti ikhale yogwirizana ndi zochitika zenizeni. Itha kuwonetsetsa kuti ma electromagnetic coupling amathandizira kwambiri pamlingo womwewo. Coils kupatsidwa ulemu ndi 99.99% ya T2 amakona anayi mkuwa mapiringidzo anapanga, kupatsidwa ulemu koyilo kunja insulating electrostatic kutsitsi ndondomeko epoxy utomoni insulating wosanjikiza wa mphamvu mkulu, kuthamanga zosagwira insulating wosanjikiza ndi wamkulu kuposa 5000V .

Chipinda chamkati cha coil induction chimapangidwa ndi zoyera za corundum, ndipo kunja kwa mzerewo ndi pakati pa ma coil amaikidwa ndi simenti yotsutsa (American Union Mine), yomwe ingathandize kuteteza ndi kuteteza kutentha. Panthawi imodzimodziyo, mphamvu yazitsulo zoyera za corundum ikuwonjezeka, ndikupewa bwino mipope yamkuwa kuti isawonongeke.

Madzi onse mkati ndi kunja kwa sensa amasonkhanitsidwa muzitsulo ziwiri zosapanga dzimbiri zosapanga dzimbiri, zomwe zimagwirizanitsidwa ndi madzi akuluakulu olowera madzi ndi mapaipi otuluka. Madzi osungira madzi osapanga dzimbiri ndi okongola komanso othandiza, omwe amatha kupeŵa mogwira mtima chikoka cha kutentha kwa coil induction chifukwa cha kuwonongeka kwa chitoliro cha madzi ndi kutsekeka kwa njira yamadzi.
